n 46 Claims, This invention relates to apparatus for'processe ing fruit,and more particularly the invention relates to an apparatus for halving,peeling, and pitting peaches and other fruit, and particularlyclingstone peaches; 1 r

The main and various ancillary features of'the present invention areshown, for purposes of exemplification, in a single, organized automaticmachine adapted to halve whole fruits, specifically peaches, positionedtherein one at a'.time, andwherein automatic mechanism is present forfirmly. holding each peach in precise positionwhile the stem cavitythereof is peeled, andduring which holding operation the peach issevered,

and the severed halvesconveyed-to mechanism to deposit the separatehalves into holding mechanism, wherein each half is first pitted, andthereafter peeled, and, subsequently, mechanism isprovidedfor-discharging the pitted and peeled halved fruit from themachine while retaining the peel inthe holding mechanism, the peel beingsubsequently discharged at a scaveng ng station-allof the foregoingsteps occurring in synchronous, sequential manner. certain of theaspects of the present invention are applicable broadly to any type, ofma chineautomatic or otherwise -whereas certain other aspects of thepresent invention comprise improved details of construction on themachine disclosed in the copending-applicationflof Ray; mond L. Ewaldand Henry Af'Skog, "Serial No". 185,332, filed January "7, 1938, nowPatent 2,28Q,813,, granted April 23,1942.

i ongthe'objects of the present invention are to provide a singleautomatic'fma chirieadapted to'receive a succession of wholepeachesj'pan ticularly clingstone peaches, which are preferablyprecisely positioned into holding mechanism of the machine by hand andwherein the mecha'- nism of the machine.thereaftersubstantially andimmediately grasps axwhole peach and retains it in this precise positionforfcoriveyantze to mechanism iOnautomaticalIy processing" the peach; toprovide an organized mechanism'ior more precisely,-firmly, and quicklyhandling a succession of peaches from the time each is positioned byhand into the machine'to the @time the peach is discharged from themachine after undergoing the 'various' processing operations thereon;-to provide means for correctly positioningf' the whole peach in themachine and maintaining control of the certain alinement of the wholepeach in themachine relative to various mechanisms operativethereon'whe'reby. to
